Description
Two OPTO-isolated inputs and twelve ISO-Drive™isolated outputs. Offering device protection and excellent flexibility, all in one product.
PRO-BUF-2 Intelligent Type Approved NMEA Buffer
Two OPTO-isolated inputs and twelve ISO-Drive™isolated outputs. Offering device protection and excellent flexibility, all in one product.
Introducing the Actisense® PRO-BUF-2, the intelligent, type-approved PRO range buffer.
The PRO-BUF-2 is rugged, with a stainless steel housing, and provides isolation on all inputs and outputs. With two NMEA 0183 inputs, twelve NMEA 0183 outputs, a bi-directional serial port and an Ethernet port, the PRO-BUF-2 is a perfect solution for larger leisure vessels, commercial shipping and is a great addition for systems that require type-approved devices.
The PRO-BUF-2 is designed to suit the majority of NMEA 0183 systems and ready to go ‘out of the box’ by simply hard-wiring the two-mode inputs as required.
The Intelligent NMEA 0183 Buffer manually configurable basic modes of operation include variations of buffer modes, intelligent auto-switch, and combine modes.
For all other configurations, leaving the mode inputs floating selects the ‘User Configuration Mode’. The web-based configuration tool allows full customisation of the PRO-BUF-2, and is compatible across all popular Operating Systems. Using the web-based configuration tool allows for fine-tuning of the data available on each output.
To make installation quick and simple the PRO-BUF-2 features 2-part pluggable connectors that allow the use of screw terminals*, and a professional DIN Rail mounting system (DIN Rail not included). The device can also be mounted directly to the bulkhead.
Helpful LEDs indicate power, data in, data out, and the alarm status to aid diagnostics.
Data statistics and load indication via the web tool provide a real-time view of data.

- PRO-BUF-2
Buffers are typically used to distribute an instruments data into multiple connected listeners. Connecting multiple listeners directly to a talker can be problematic, including current drive issues and wiring issues. Using a buffer removes these issues, and allows for safe, strong distribution of your data.
An example of this could be on a commercial vessel with one GPS and multiple NMEA 0183 displays or 4 display ECDIS. To get all of these displays to receive your GPS data, you can use a buffer to output to each display, whilst being fully isolated.
With the PRO-BUF-2, the data can be filtered, passed or blocked and monitored, giving greater flexibility and control over all instrument data.
